# How to make a photo backdrop paper clip with vibe CAD

Join a lightweight paper backdrop to a measured display-board edge using a loose sliding sleeve. The design captures a paper fold without relying on a spring clamp or supporting lights, cameras or a large suspended backdrop.

## Make this project
An unvalidated paper-positioning accessory for a small tabletop setup, not a structural clamp.

This recipe has not been physically validated. Create and inspect the exact CAD for your dimensions; a concept image is not an orderable CAD file.

## 1. Measure
- Display-board thickness and edge shape.
- Total thickness of the folded backdrop paper.
- Available edge depth behind the photographed area.
- Clip width that stays outside the camera frame.

## 2. Give your CAD agent this prompt

Create a loose backdrop-paper sleeve with board_thickness, paper_stack_thickness, sleeve_clearance, sleeve_depth, clip_width and edge_radius. Ask for missing dimensions and the board's actual edge profile. Use a rounded open channel that slides over the paper-covered board. Add a short channel coupon. Limit the design to positioning lightweight paper on a tabletop board, with no spring-force or equipment-support claim.

## 3. Model and inspect
1. **Measure the complete sandwich** — Fold the backdrop over the board exactly as intended. Measure board and paper together, including any doubled crease near the edge.

2. **Build the sleeve section** — Create a loose U-shaped section with rounded entry corners. Keep its inside faces simple so paper does not meet ridges or lettering.

3. **Set the visible footprint** — Extend the section only far enough to position the paper. Preview two sleeves at the board edges and move them outside the intended photograph.

## 4. Check the prototype
- Evaluate a short channel coupon against a disposable paper sample.
- Inspect the entry corners for edges that could crease or score the backdrop.
- Review the camera framing with full-size paper outlines of the clips.

## Avoid this mistake
Measuring the bare board alone leaves no room for the folded paper and encourages forcing the sleeve into place.

## Choose the material
PLA provides a rigid prototype option. PETG can be considered, but neither material establishes a predictable clamping force.

**No payment at submission.** Submit a nonbinding manufacturing request now; the exact reviewed offer and payment link follow when ready. Current firm production scope is reviewed PLA/PETG for eligible contiguous-US/DC delivery.

### Agent submission steps
1. **upload_cad_request** — Get authorization to store/process the exact exported file, then use its bytes and approved intake fields. Save the returned request ID and file SHA-256.

2. **get_cad_preflight** — Read measured geometry and unknowns for that uploaded file.

3. **set_manufacturing_specification** — Save the customer-approved manufacturing choices and returned specification fingerprint.

4. **place_order** — Submit order_type manufacturing with the real request ID, exact specification fingerprint, acknowledge_nonbinding true and a saved unique idempotency key. Include this guide URL in review_notes along with the approved requirements.

5. **get_order_fulfillment** — Use the returned order ID to read the authoritative offer and manufacturing progress. A recipe URL alone never identifies an order.

Reconcile an uncertain result before retrying. Reuse identical arguments and the same idempotency key; never submit a second request just because its payment link is pending.
